Meters

Colorimeters use a light source of a particular wavelength, a color-changing, colorimetry reagent, and a light detector to determine the concentration of a particular substance, usually in an aqueous or water-based sample. After mixing the sample with a specific color-changing reagent, the sample is place within the sample chamber of the colorimeter, where light of a specific wavelength is passed through it. The desired substance’s concentration measurement will react with the reagent to change the color of the sample. The concentration of the parameter is proportionate to color change intensity. Since different chemical substances absorb different visual light frequencies, the detector can determine the absorbance of the light passed through the sample based on the intensity of the sample color. We stock both single-parameter and multi-parameter colorimeters.

We carry a complete line of conductivity meters for your testing needs. We stock all the best brands and offer you a variety of options from single-parameter conductivity meters, to multi-parameter meters.

Fluorometers are commonly used in chemical dosing control systems of cooling towers and boilers. Fluorescent dyes are added to the chemicals and their levels provide an indication as to whether the chemical dosing is in the desired range. Fluorometers can also be used for tracking product quality through a distribution system to ensure dilution does not occur. Using fluorometers to monitor and control industrial processes is an easy way to improve quality and service, increase efficiency, and reduce operating costs.

We distribute pH meters from all the top brands and keep stock of many popular pH meters. Benchtop or portable, hanheld models are all available. If you can't find what you're looking for, please contact us and we can get it for you.

Turbidimeters are used to measure the relative clarity of a fluid by measuring the amount of light scattered by particles suspended in a fluid sample. Suspended solids obstruct the transmittance of light through fluids. The turbidity of a sample may be due to a single chemical substance or a combination of several. A turbidimeter measures this obstruction to determine the haziness, or intensity of light, in a sample, in nephelometric turbidity units (NTU). A cloudy solution has a high haziness value, while a relatively clear solution has a low value.
